Convert Integer[] to int[] array

由 三世轮回 提交于 2019-12-17 15:46:54
问题 Is there a fancy way to cast an Integer array to an int array? (I don't want to iterate over each element; I'm looking for an elegant and quick way to write it) The other way around I'm using scaleTests.add(Arrays.stream(data).boxed().toArray(Double[]::new)); I'm looking for an one-liner but wasn't able to find something. The goal is to: int[] valuesPrimitives = <somehow cast> Integer[] valuesWrapper 回答1: You can use Stream APIs of Java 8 int[] intArray = Arrays.stream(array).mapToInt(Integer

Java Wrapper equality test

问题 public class WrapperTest { public static void main(String[] args) { Integer i = 100; Integer j = 100; if(i == j) System.out.println("same"); else System.out.println("not same"); } } The above code gives the output of same when run, however if we change the value of i and j to 1000 the output changes to not same . As I'm preparing for SCJP, need to get the concept behind this clear. Can someone explain this behavior.Thanks. 回答1: In Java, Integers between -128 and 127 (inclusive) are generally

Objective-C Wrapper for CFunctionPointer to a Swift Closure

由 杀马特。学长 韩版系。学妹 提交于 2019-12-17 12:35:13
问题 I am playing with Swift and noticed that Swift does not allow to create CFFunctionPointers. It can only pass around and reference existing ones. As for example CoreAudio requires CFunctionPointer to certain callbacks therefore I cannot use pure Swift. So I need to use some Objective-C trampoline or wrapper here that takes a Swift Closure as a parameter as well as the original callback prototype and then can be assigned to be the callback, but the actually action happens in Swift and not

问题 i have implemented an error level analysis algorithm using c++(opencv version 2.4) and i want to build a python wrapper for it using cython. I have read some part of the documentation of cython for c++ but it did not help me and moreover i did not find any extra information for implementing the wrapper online. It would be really great if someone could guide me and help me solve this problem. This is my code for which i want to build a pyhton wrapper: #include <opencv2/highgui/highgui.hpp>

wrapper class for STL stream: forward operator<< calls

问题 I'm currently writing a wrapper for STL stream to synchronize write calls from multiple threads. I have the following (simplified) code: class Synchronize { private: std::stringstream ss; public: void write(std::string& str) { // locking ... ss << str; // unlocking ... }; // other stuff .. }; Synchronize& operator<<(Synchronize& o, std::string& str) { o.write(str); return o; } Synchronize& operator<<(Synchronize* o, std::string& str) { o->write(str); return *o; } Its now possible to call the

Persisting time ojects as entities instead of value types?

由 烈酒焚心 提交于 2019-12-13 17:14:50
问题 I'm using Joda Time DateTime to handle date and time. I persist objects of this kind using the class PersistentDateTime bundled in the jodatime hibernate code. I have large collections of DateTime objects, and I currently persist them in the following way (an excerpt of an hibernate mapping file follows): <set name="validInstants" sort="natural"> <key column="myobject_id"/> <element column="date" type="myproject.utilities.hibernate.types.PersistentDateTime"/> </set> Doing so, i.e. storing

Java — Primitive Counterpart of Byte, Integer, Long, etc. in template

由 最后都变了- 提交于 2019-12-13 12:24:27
问题 BACKGROUND : I am trying to implement a tiny template, i.e. generic class, which would allow me to achieve a pass-by-reference functionality as follows. public static class Ref<T> { T value; public Ref(T InitValue) { this.set(InitValue); } public void set(T Value) { this.value = Value; } public T get() { return this.value; } } So, I could define a function that takes a 'Ref' where the value can actually be changed, e.g. public static void function(Ref<Byte> x) { x.set((byte)0x7E); } The
